in your home town, do the road signs give the full name of the airport? or the abbreviated, three letter IATA code? here, the big green roadway signs say 'Kennedy Airport' and 'LaGuardia Airport', with the little signs on the side depicting a plane and 'JFK' or 'LGA'.

how does it work by you? would people understand where they were going if they saw a sign that said 'LHR' or 'FRA' on it?

In Seoul, South Korea, signs for the Domestic Airport are listed as Kimpo airport, or at times, Gimpo Airport. There is some confusion in the translation between whether the name should be spelt with a "G" or "K". Of course, they also contain the airport name in Korean writing!
